INTRODUCTION. After Willoughby Smith discovered the photoconductivity of selenium (Se) in 1873, Charles Fritts constructed the first solid-state solar cells in 1883 by sandwiching Se film between a metal foil and a thin gold (Au) layer () spite the low preliminary power conversion efficiency (PCE) of <1%, these early discoveries initiated the research of …
Selenium (Se) solar cells were the world''s first solid-state photovoltaics reported in 1883, opening the modern photovoltaics. However, its wide bandgap (~1.9 eV) limits sunlight harvesting. Here, we revisit the world''s oldest but long-ignored photovoltaic material with the emergence of indoor photovoltaics (IPVs); the absorption spec-
Employing sunlight to produce electrical energy has been demonstrated to be one of the most promising solutions to the world''s energy crisis.
